Via Greg Sargent at TPM Muckraker, Senator Sam Brownback scores an early victory in the fight to be the favorite "social conservative" Republican presidential primary candidate:

CNN is reporting that Kim Lehman, the current president and executive director of Iowa Right to Life, has "signed on to Brownback's upcoming Iowa leadership committee."

Brownback's new supporter wasted no time taking a veiled shot at the other GOPer who's making a bid for the same socially-conservative voters coveted by Brownback: Mitt Romney. In a statement, Lehman said: "While other candidates are in the process of defining and refining their position at the start of this campaign, Senator Brownback has been principled, consistent and unwavering in his support for the right to life."
